The Trapstrap is a simple and easy-to-use device that prevents bass drums and hi-hats from sliding away during play. It’s designed specifically to anchor the bass drum and/or hi-hat to the throne. The product, which is fully adjustable in length, attaches to the bass drum tension rods or to the legs of a hi-hat stand. Two Trapstraps are required to anchor both instruments. List price: $15 for one Trapstrap, $25 for two.
